Product details
Overview
689-4 from Microsemi is a fast recovery rectifier assembly in doubler configuration, housed in an electrically isolated aluminum case. It delivers 15 A average DC output current at TC = 55 °C, supports 400 V VRWM, exhibits 500 ns reverse recovery time, and operates up to 150 °C junction temperature - used in high-reliability AC/DC front-end power supplies for industrial motor drives.
For engineers reviewing the 689-4 datasheet, 689-4 pinout, 689-4 application, or 689-4 equivalent, key selection criteria include its 400 V working peak reverse voltage, 500 ns trr, 15 A IO rating at 55 °C, thermally robust aluminum package with RθJC = 6.0 °C/W, and RoHS-compliant matte tin terminals.
Technical Context
This device integrates two fast recovery diodes in a single aluminum-cased doubler topology, enabling full-wave rectification without external center-tapped transformers. Its controlled avalanche characteristics and 150 A nonrepetitive surge capability support transient-heavy industrial line inputs.
The 689-4 operates with VF = 1.2 V per leg at 10 A and IR ≤ 10 µA at 25 °C (VRWM = 400 V), maintaining low conduction loss and minimal leakage across temperature - critical for efficiency-sensitive 50/60 Hz rectification stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 400 V - maximum continuous reverse voltage before breakdown; defines safe AC input voltage headroom |
| IO (TC = 55 °C) | 15 A - max average DC output current with heatsink at 55 °C case temperature |
| trr | 500 ns - reverse recovery time at IF = 1.0 A, IRM = 1.0 A; limits switching losses in line-frequency applications |
| VF @ 10 A | 1.2 V per leg - forward voltage drop determining conduction loss and thermal dissipation |
| RθJC | 6.0 °C/W - thermal resistance from junction to case; enables direct mounting to heatsink for thermal management |
| TJ max | 150 °C - maximum allowable junction temperature; sets derating envelope for long-term reliability |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery doubler rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15EWH04-M3 | Single-die TO-247 package; 400 V VRWM, 15 A IO, 50 ns trr - faster but lower surge rating (100 A IFSM) | Lacks integrated doubler topology and aluminum isolation; requires external layout for full-wave configuration | Select when board space is constrained and discrete layout control is preferred over integrated mechanical robustness |
| IXYS MBR1545CT | TO-220AB dual Schottky; 45 V VR, 15 A IO - not suitable for 400 V line applications; no avalanche rating | Designed for low-VF DC-DC outputs, not AC line rectification; incompatible with 400 V reverse stress | Reject for 689-4 replacement; only consider for low-voltage secondary-side rectification where VRWM < 50 V applies |
Compared with VS-15EWH04-M3 and MBR1545CT, the 689-4 uniquely combines 400 V VRWM, doubler integration, 150 A surge tolerance, and electrically isolated aluminum packaging - making it irreplaceable in high-surge, high-isolation, line-frequency rectifier roles.

FAQ
What is the maximum working peak reverse voltage (VRWM) for the 689-4?
The 689-4 has a VRWM of 400 V, confirmed in the RF01151 Rev A datasheet's Part Nomenclature table and Electrical Characteristics section. This rating defines the peak reverse voltage the device can sustain continuously without breakdown under normal operating conditions, and corresponds to the "-4" suffix in the 689-4 part number.
Does the 689-4 have a center tap or doubler configuration?
The 689-4 is a doubler configuration, as indicated by the "D" in the part nomenclature legend (Page 2 of RF01151 Rev A). Its terminal markings are AC1, AC2, +, and – - confirming two AC inputs and a common cathode/anode pair for full-wave rectification without a center tap.
What is the reverse recovery time (trr) specification for the 689-4?
The 689-4 has a reverse recovery time of 500 ns, measured at IF = 1.0 A, IRM = 1.0 A, and IR(REC) = 0.5 A, per the Electrical Characteristics table on Page 3 of RF01151 Rev A. This value is specific to the 689-series fast recovery variant and distinguishes it from the slower 681-series standard recovery rectifiers.
Is the 689-4 RoHS compliant?
Yes, the 689-4 is RoHS compliant, denoted by the "e3" suffix in its full designation (689-4(e3)). The datasheet states RoHS-compliant versions are available and specifies matte tin plating for terminals, meeting EU Directive 2011/65/EU requirements for lead-free manufacturing.
What is the thermal resistance from junction to case (RθJC) for the 689-4?
The 689-4 has a thermal resistance of 6.0 °C/W from junction to case, as listed in the Maximum Ratings table on Page 1 of RF01151 Rev A. This low RθJC enables effective heat transfer to an external heatsink mounted directly to the aluminum case, supporting its 15 A IO rating at TC = 55 °C.
